Abstract
An elastic wave device includes an elastic wave element including a piezoelectric substrate with a first main surface and a second main surface that face each other, an IDT electrode disposed on the second main surface of the piezoelectric substrate, a support disposed on the second main surface of the piezoelectric substrate so as to surround the IDT electrode in plan view, and a cover that is disposed on the support and seals the IDT electrode together with the support and the piezoelectric substrate, a mounting substrate above which the elastic wave element is mounted, and a sealing resin that is disposed on the side of the side of the upper surface of the mounting substrate and seals the elastic wave element. A thickness of the mounting substrate is less than a thickness of the sealing resin that corresponds to a distance from a surface of the sealing resin in contact with the upper surface of the mounting substrate to a surface of the sealing resin on an opposite side of the mounting substrate.
